Hi,
You can create a ‘Service’ and assign a random integer to a blackboard value and then on each task, use ‘blackboard condition’ decorator to check that integer value. Here, take a look at this very simple setup for a better understanding;
Blackboard
Behavior Tree
Service
Assign the service value to blackboard value.
First Task
Note that in this approach, the selector only picks one random task to execute. Hope it help.
Regards,
